Hi,

Sir, Did you used correct server API key and Pass while adding it on WHMCS panel ?
Please allow the virtualizor ports from 4081 to 4085 in the firewall on the WHMCS server you can add it from below command.
iptables -I INPUT 1 -p tcp -m tcp --dport 4081:4085 -j ACCEPT        (for iptables)

firewall-cmd --zone=public --permanent --add-port=4081-4085/tcp    (for firewall)
firewall-cmd --reload

Also, check the server username and password is correct or not, You can check it from Admin panel >> Configuration >> Server info.


Let us know if you need any further assistance.



I already got the Key and the Key password that is in Virtualizor Administration -> Configuration -> Server Information and got it there, but it gives the same problem, then I got the key and put it in Username and Key Password and put it in password in WHMCS.

I thought I was putting the wrong module in WHMCS but I tested the 2 types of module too and it gave the same problem, it talks about the ports and it talks about the credentials.

I got the module for resale and created an API credential then I got the API Key and put it in username and got the API Password and put it in password in WHMCS I clicked on test connection and the problem occurred.]]> Wed, 11 Jun 2025 21:29:45 GMT https://www.softaculous.com/board/index.php?tid=20196&tpg=1#p59580 <![CDATA[FAILED: Could not connect to Virtualizor.]]> https://www.softaculous.com/board/index.php?tid=20196&tpg=1#p59577
